MELVILL AND STANDEN : SHELLS EROM LIEU. 279 



One of the gems of the collection. Solid, in form fusiform, 

 eight-whorled, two whorls being plain brown, small, apical, while 

 the remainder are usually obtusely ribbed longitudinally, crossed 

 with fine spiral lines, the colour is pale violet or purple, with a 

 broad fulvous-yellow zone encircling each whorl, the lip is 

 extremely incrassate, striped with brownish yellow, and the 

 sinus is hardly perceptible.

 the bright coloration).
